SPECIFICATION forming part of Letters Patent No. 494,905, dated Apr-i14, 1893. I

Application filed May 26; 1892. Serial No. 134,476.- (No model.)

To all whom it may concern: Be it known that I, ARMIN TENNER, engineer,a citizen of the United States of America,

residing at 13 Grossbeerenste, Berlin, in the German Empire, haveinvented new and useful Improved Oartridge-Loadin g Machines, of

which the following is a specification.

The subject matter of the present invention is a cartridge loadingmachine having a step like movement of the rotary table with itsclamping bearings in 'which the'cartridge casesare' held and aresuccessively. brought beneath the tools or loading devices so that byeach simultaneous operation of the same a cartridge is completelyloaded. A device is combined with the rotary table consistingessentially of radially movable slides in order to bring felt wads cutout by hand or machine over the mouths of the cartridge cases at themoment when the same come beneath the punch immediately following thepowder charging device. The same device can also be used for loadingball cartridges.

The invention also includes gearing for the rotary table: a reamer inconnection with the powder charging device; a shot measure a device forupsetting the edge of the cartridge case and the well known devices forcutting, stamping and inserting the upper wad.

Figure 1 is a side view of the cartridge loading machine forshotcartridges. Fig. 2is'a vertical section; Fig. 3 a top view partly insection. Fig. 4is a part horizontal section showing the clamps for thecartridge cases in top view. Fig. 5 is an elevation of the tool carrierin its lowest .position, five cartridges being shown in section todemonstrate the operation of the parts. Fig. 6 is a section of thelasttool for upsetting or turning down the edge of the cartridge case,

plate A and two standards B B connected by v a yoke C, the tool carrierD being guided in prismatic or other guide ways in the arms of the same.To the front 'of and beneath the tool carrier D, which moves vertically,is a feed wheel or rotary table E in the center of which is the fixedstandard A which carries a stationary plate A Between the standard A andthe conically borednave E'- of the rotary table E is an exteriorilyconical annular member- F which can be so adjusted by means of screws 1)q that a considerable friction can be produced on the surface of thenave in order to prevent all independent rotation of thetable E underthe impulse of the ratchet and pawl driving device. The movement of thisdevice is in common with the stroke of the tool carrier D, derived fromthe horizontal shaft G. which is driven by appropriatestraps or in othersuitable manner. The eccentric a with eccentric rod 1) which is inconnection with the slide (1 with spring pawl c serve to transmit themovement of the shaft G so that the ratchet wheel 6 connected to thenaveE of the rotary table E receives its intermittent movementduringeach semi-rotation of the shaft G. The tool carrier D is reciprocated invertical plane by thesame being connected by the rod H to. the crank Iof the shaft G (Fig. 2). I

The circumference of the, rotary tableE or the edge of the upper plateof the samea'nd the annular part E beneath the same is, as will be seenfrom Figs. 2 and3 so recessed to form the part of a cartridge bearing11, that the cartridge cases can be inserted from the exterior to betransported under the various tools during the rotation of the table E.

The number of recesses 2' correspond with the number of teeth in theratchet wheel 6 each recess corresponding with a clamping leverjmovingaroundthe fulcrumj within the rotary table E and operated by meansof a suitable springf.

The flange U arranged at appropriate height above the base plate and.running almost entirely around the same serves to support thetransported cartridge cases so that the same cannot fall out until theyreach the open space Z where as is shown in Fig. 4 the flange isinterrupted so as to allow the finished cartridge to fall out ofthemachine. The clam ping lovers] are held open for a part of their traveland the action of their springs over- :00 come by the shorter arms ofthe same, which carry antifriction rollers j coming into contact with anextension u of the flange U which runs from the opening Z to the pointtoward the tool carrier, the clamping levers:

are always closed as the flange U lies lower than the way described bythe antifriction rollers j so that the springs f can press the I bentends of the levers j onto the cartridges.

After the cartridge cases have beenplaced 1n the open bearings and theclamping levers have securely gripped the same they are su'ccessivelytransported beneath the tools carried'by the tool carrier, the distanceof the same from each other being determined by the distance of fivesuccessive cartridge cases 1, Q, 3, 4, 5 from each other.

The first device which comes into'operation is the powder chargingdevice attached to the powder receptacle N. The construction of thisdevice is similar to that described later on for the shot chargingdevice and for the reame'r or Widener. The latter device serves torestore any cases, which may have become irregular, as to correct'formbefore charging same, and consists of a conical tubular spindle 'mattached to one of the sides of the plate D. Figs. 1 and 5, and fittingover the lower end of the powder-feed tube 11.. By partially insertingthis conical hollow spindle in the mouth of thecartridge case, the mouthof the same is cylindrically enlarged during the charging of the casewith powder.

' The punch 0 is the second device which comes into operation on thetool earrierD descendingin order to force a felt wad 7', cut out bymeans of a special device, into the cartridge case (2) already chargedwith powder.

' On the platePai-e placed a series. of wad carrier slides s radiatingfrom the center of the table, each provided with a ring shapedreceptacle .on the outer end to hold the wad, as

shown in Fig. 2, where the slides are in sec-- tilon, and in Fig. 3,where they are shown in p an. These slides are operated to present thewa carried thereby to the cartridge at the proper time and place, by ajcam groove s in the under face of the plat'e A, the shape of whichgroove is shown in Fig. 3, into which extends rollers s projecting fromthe upper surface of the said slides... The groove is circular except atone point where it diverges outwardly and this causes the slides in therotation of the plate P to follow the course of the groove which thus atthe proper time advances the slide to present the wad. The spring stop 0is clearly shown in Fig. 5, right hand side; so

that as soon .as a cartridge case during. the

rotary movement of the table comes into the position 2 the tube sontheslide s will be over the mouth of the cartridge case so that thepunch 0 can drive the wad inthe tube s onto the powder charge. ,In'thethird position or above the cartridge 3 (Fig. 5) is the stationarytube-w of the shot measurer. The

The wads are fed to the slides by hand.

in all essential points with the powder measuring device is providedwitha slide D (Fig. 2) which in combination with the plate D is movedvertically between the plate W and the casing W said slide having aninclined opening t and an adjustable piece D in order p to adjust thesize of the shot measurer. In the uppermost position of the slide 1),the opening 15 comes into communication with the inclined canal leadingfrom the shot magazine W and receives the requisite charge of shot whichon the descent of the parts will be filled into the cartridge (3; bymeans of the tube or channel 10, As n some cases, especially with largeshot, a shot falls partly half into the openingtand would on the furthermovement of the slide be cut in two, I provide a piece of metal 15'under spring action so arranged that the forward surface willas a rulebe flush with the surface of the slide and form a yielding edge. Inconsequence of an incline on the piece 15 and the continued descent ofthe slide the superfluous shot will be forced into the space so formedbut will by the next movement of the slide at once fall into theopeningt when the-same during the upward stroke of the slide comesopposite to the said shot. A modification of this auxiliary device whichcan be omitted in the powder charging device (N, n) is represented inFig. 7. In this case the lower surface 15 of the charging canal is madeto yield being held by the spring i the bent end of which prevents. thesuperfluous shot'from falling out. As soon as the cartridge cases are asbefore described charged with powder and shot with intermediate felt wadthe same come beneath'a second punch 0' (position 4) which acts similarto the punch 0 and which firstcuts a cardboard wad out of a suitablytransported band and then drives the same onto the shot charge. Theratchet device for transporting the cardboard band or strip and also astamp 0 attached to the tool carrier, for numberinglthe wad is shown inFig. 2 and partially in Fig. 3 butbeing well -known to. all versed inthe art requires no further description. Both punch 0 an punch 0' are asshown in Fig. 5 yieldingly attached in tubes to the reciprocatingtoolcarrier so that the blow is not sudden but yielding and thus allundue strain on the parts avoided. In the fifth and last position(cartridge 5 Fig. 5) the new upsettingv device or toolfor bending overthe edge of the cartridge case onto the upper wad comes into action andconsists of a spindle v with upsetting tool it inserted in the head 22of the same. The spindle u-has rotary motion and reciprocates verticallyand is'attached by the bearings V and V to the frame and receives itsrotary movement in any. suitable manner from the mechanism. During therotation. of the rotary table the spindle is so far raised that the headwill be above the way described by the cartridge cases. A spring stop 0connected tothe tool carrier. will, when the. latterreaches the end ofit:

downward hub, drive the spindle or mandrel down so that the notches inthe tool 1/. in the' head Q) will press on the upper edge of the.

cartridge case with increasingforce. The pressure in con unction withthe rotary motion transmitted to the tool will upset or turn over theedge of the cartridge case so as to I securely hold the cardboard wadabove the f to the clamping As soonas the finished cartridge is movedwith the rotary table E 'a distance equal to onetooth of the ratchetwheel, the same will fall through theopening Z as. the same is on theone hand no longersupportedby the flange U and on the other hand isreleasedfromthe grip-of the clamping lever f, the roller 3" of whichlies on the flange U.- It will be seen from the above that the cartridgeclamps will be at certain tiinesin open position ready for the insertionof fresh cartridge cases. The new felt wads arealso inserted in the wadholders s of the slide s from this side of the rotary drawn inward. K

At each rotation of theshaft G the machine will deliver a cartridgeloaded in five operations whichfallsout at the opening Zinto acollecting receptacle. Figs. 8 and 9 represent the modification -forloading ball or militarycartridges all the essential points of theforegoing machine being employed. The empty metallic shells are fed froma tubular magazine M successively, by means of awh'eel L, undersuitableborings of the rotarytable E the clamping device in this case beingomitted. The cartridge shells are raised into the cartridge bearings bya connnecting rod when the borings align said rod being operated byalever Z and a tappet wheel (Fig. 8) the tappet only being shown. Theboringsin the rotary table E'and the wheel L will correspond at eachstep of the ratchet wheel (Fig. 9). The powder feed is eflected from theopposite side of the rotary table in precisely the same manner asdescribed with reference to Figs. 1 and 7 while the bullets are drivenin by a device similar to the wad feed, the radial slides s in this caseforming the receivers s for the bullets'which when the same are abovethe cartridge cases2will bedriven intothe cartridge .eases by the punch0. 'Plledevices for feeding the shot, upsetting the upper edge, &c.
